Methods: Pretreatment FFPE tumor specimens (n = 26) were stained for CD8, PD-L1, and PD-1 by immunohistochemistry/immunofluorescence (IHC/IF), and the density and distribution of positive cells was quantified to determine the associations with anti-PD-1 response. Multiplex IF was used to test a ...
Read more →Understanding mechanisms of late/acquired cancer immunotherapy resistance is critical to improve outcomes; cellular immunotherapy trials offer a means to probe complex tumor–immune interfaces through defined T cell/antigen interactions. We treated two patients with metastatic Merkel cell carcinoma...
Read more →Background: Merkel cell carcinoma (MCC) is a rare and aggressive cutaneous malignancy. In the advanced setting, MCC is often treated with immune checkpoint inhibitors such as anti-PD-1/PD-L1 antibodies. X-ray radiation therapy (XRT) is commonly used for palliation. There is an unmet need for new tre...
Read more →Background: Immune checkpoint inhibitors (ICIs) are the treatment of choice for several cancers and can be associated with remarkable clinical benefit, but can also cause serious immune-related adverse events (irAEs). Management of rare and severe irAEs is challenged by an incomplete knowledge of th...
Read more →PURPOSE: Merkel cell carcinoma (MCC) is an aggressive skin cancer with neuroendocrine differentiation. There is an unmet need for MCC-specific blood-based surrogate biomarkers of tumor burden; circulating cell-free micro(mi)RNA may serve this purpose. EXPERIMENTAL DESIGN: Expression of miR-375 was q...
Read more →Background: Merkel cell carcinoma (MCC) is a rare but aggressive neuroendocrine skin cancer. The estimated 5-year survival of patients with metastatic disease is approximately 14%. Cytotoxic chemotherapy is associated with a modest median progression-free survival (PFS) of only 3 months. In recent s...
Read more →PURPOSE: The causative agent of most cases of Merkel cell carcinoma (MCC) has been identified as the Merkel cell polyomavirus (MCV). MCV encoded T-antigens (Tags) are essential not only for virus-mediated tumorigenesis but also for maintaining MCC cell lines in vitro. MCV Tags are thus an appealing ...
Read more →BACKGROUND: Merkel cell carcinoma (MCC) incidence rates are rising and strongly age-associated, relevant for an aging population. OBJECTIVE: Determine MCC incidence in the United States and project incident cases through the year 2025. METHODS: Registry data were obtained from the SEER-18 Database, ...
Read more →Aim: The aim of this article was to provide worldwide, population-based incidence rates for Merkel cell carcinoma (MCC). Methods: We included 11,576 cases from 20 countries for time trend analyses (1990e2007) and 11,028 cases (2.5 billion person-years) from 21 countries for the period 2003e2007 extr...
Read more →BACKGROUND: Merkel cell carcinoma (MCC) is a rare, aggressive skin cancer associated with poor survival outcomes in patients with distant metastatic disease (mMCC). In an initial analysis from JAVELIN Merkel 200, a phase 2, prospective, open-label, single-arm trial in mMCC, avelumab—a human antiâ€...
